Easy to follow emergency advice on what to do if you or someone you’re with has an asthma attack. If you use a MART inhaler, follow our MART asthma attack advice.
What to do in an asthma attack
- Sit up straight - try to keep calm.
- Take one puff of your reliever inhaler (usually blue) every 30-60 seconds up to 10 puffs.
- If you feel worse at any point OR you don’t feel better after 10 puffs call 999 for an ambulance.
- If the ambulance has not arrived after 10 minutes and your symptoms are not improving, repeat step 2.
-
If your symptoms are no better after repeating step 2, and the ambulance has still not arrived, contact 999 again immediately.

Know the signs of an asthma attack
You’re having an asthma attack if:
- your blue reliever isn't helping, or you need to use it more than every four hours
- you're wheezing a lot, have a very tight chest, or you're coughing a lot
- you're breathless and find it difficult to walk or talk
- your breathing is getting faster and it feels like you can't get your breath in properly.
You may have all of these signs and symptoms. Or you may have just some of them. For example, you may not wheeze.
Know your early warning signs
An asthma attack happens when your symptoms get much worse. This can happen quite suddenly or can build up gradually over a few days.
You can stop an asthma attack before it happens. or make it less serious so you don’t end up in hospital, by recognising when your symptoms are getting worse.
When to call 999
Don’t delay getting help if you have an asthma attack. Call 999 if your reliever isn’t helping, or lasting four hours, or you’re worried at any time.
An asthma attack is a real emergency and could be life-threatening. Getting help when you need it is so important, to make sure you’re treated quickly. Never think you’re wasting anyone’s time.
When to see your GP
If you managed your asthma attack with your blue reliever inhaler, and your symptoms improved, you still need to make an urgent same-day appointment with your doctor. You need an urgent asthma review after the attack.
